First of all, thanks for that essay. I was blown away by the movie.
I would say that what needs to change is that we need to move past Liberalism, with equality and liberty as the 'twin pillars of justice', as an approach to justice. For one thing, as its critics point out, to tout 'equality' is to acknowledge the 'other'ness that underlies it. It must be clear to anyone who gives it a moment's thought that constraints on liberty--such as equality--generate justice, not liberty itself (which is people doing whatever they want to do).
In "A New Liberalism" the observation that human beings have no choice but to effect choices is the starting point for a new approach to justly governing society. To respect one another's capacity to choose is to recognize one another as fellow humans; to act otherwise is to assert some unverifiable claim diminishing the humanness of the other being(s) involved. At the minimum, to respect others' humanness is to refrain from killing, harming, coercing, stealing, or manipulating (which includes lying, cheating, etc.) in effecting any choice. Mutual respect for one another's capacity to choose would generate the maximum liberty that coexisting people can share simultaneously.
